ATOS放大器增加信號幅度或功率的裝置，它是自動化技術工具中處理信號的重要元件。 放(fang)大(da)器的(de)(de)(de)放(fang)大(da)作用是(shi)(shi)用輸(shu)入信號(hao)控(kong)制能源來(lai)實現(xian)的(de)(de)(de)，放(fang)大(da)所需功耗由能源提(ti)供。對(dui)于(yu)(yu)線性(xing)放(fang)大(da)器，輸(shu)出(chu)(chu)就是(shi)(shi)輸(shu)入信號(hao)的(de)(de)(de)復現(xian)和增強。對(dui)于(yu)(yu)非線性(xing)放(fang)大(da)器，輸(shu)出(chu)(chu)則與輸(shu)入信號(hao)成一定函數關系(xi)。 ATOS放大器E-ME-AC-05F安裝方式為歐板式，用于不帶傳感器的比例閥，以調整閥芯位置，從而使流量或壓力與輸入信號成正比。 
ATOS放大器E-ME-AC-05F的作用： 放(fang)大(da)器是能把(ba)輸入訊號(hao)的電(dian)壓或功率放(fang)大(da)的裝(zhuang)置(zhi)，由電(dian)子(zi)管或晶體管、電(dian)源變壓器和(he)其(qi)他電(dian)器元件組成(cheng)。用在通訊、廣播、雷達、電(dian)視、自動(dong)控(kong)制等各種(zhong)裝(zhuang)置(zhi)中。 放大器用(yong)于發(fa)射(she)機的(de)(de)末級，作用(yong)是將高(gao)頻(pin)已調波信(xin)(xin)號(hao)進行(xing)功(gong)率(lv)放大，以(yi)滿(man)足發(fa)送(song)功(gong)率(lv)的(de)(de)要求(qiu)，然后經過(guo)天線將其輻(fu)射(she)到(dao)空間，保證在一定區(qu)域(yu)內的(de)(de)接(jie)收機可以(yi)接(jie)收到(dao)滿(man)意的(de)(de)信(xin)(xin)號(hao)電平，并且(qie)不干擾相(xiang)鄰信(xin)(xin)道(dao)的(de)(de)通信(xin)(xin)。 高(gao)(gao)頻(pin)(pin)功(gong)(gong)率(lv)(lv)放(fang)(fang)(fang)大器(qi)(qi)(qi)(qi)(qi)是(shi)(shi)通(tong)信(xin)系統(tong)中(zhong)發送(song)裝置的(de)(de)(de)(de)重要組件(jian)。按其工(gong)作(zuo)(zuo)(zuo)頻(pin)(pin)帶(dai)的(de)(de)(de)(de)寬(kuan)窄(zhai)(zhai)劃分(fen)為(wei)(wei)窄(zhai)(zhai)帶(dai)高(gao)(gao)頻(pin)(pin)功(gong)(gong)率(lv)(lv)放(fang)(fang)(fang)大器(qi)(qi)(qi)(qi)(qi)和寬(kuan)帶(dai)高(gao)(gao)頻(pin)(pin)功(gong)(gong)率(lv)(lv)放(fang)(fang)(fang)大器(qi)(qi)(qi)(qi)(qi)兩種(zhong)，窄(zhai)(zhai)帶(dai)高(gao)(gao)頻(pin)(pin)功(gong)(gong)率(lv)(lv)放(fang)(fang)(fang)大器(qi)(qi)(qi)(qi)(qi)通(tong)常以具有選頻(pin)(pin)濾波(bo)(bo)(bo)作(zuo)(zuo)(zuo)用(yong)的(de)(de)(de)(de)選頻(pin)(pin)電(dian)(dian)(dian)路(lu)作(zuo)(zuo)(zuo)為(wei)(wei)輸(shu)(shu)(shu)出(chu)(chu)(chu)回(hui)(hui)路(lu)，故又稱為(wei)(wei)調(diao)(diao)諧(xie)功(gong)(gong)率(lv)(lv)放(fang)(fang)(fang)大器(qi)(qi)(qi)(qi)(qi)或諧(xie)振功(gong)(gong)率(lv)(lv)放(fang)(fang)(fang)大器(qi)(qi)(qi)(qi)(qi)；寬(kuan)帶(dai)高(gao)(gao)頻(pin)(pin)功(gong)(gong)率(lv)(lv)放(fang)(fang)(fang)大器(qi)(qi)(qi)(qi)(qi)的(de)(de)(de)(de)輸(shu)(shu)(shu)出(chu)(chu)(chu)電(dian)(dian)(dian)路(lu)則是(shi)(shi)傳輸(shu)(shu)(shu)線(xian)變壓器(qi)(qi)(qi)(qi)(qi)或其他(ta)寬(kuan)帶(dai)匹配電(dian)(dian)(dian)路(lu)，因(yin)此又稱為(wei)(wei)非調(diao)(diao)諧(xie)功(gong)(gong)率(lv)(lv)放(fang)(fang)(fang)大器(qi)(qi)(qi)(qi)(qi)。高(gao)(gao)頻(pin)(pin)功(gong)(gong)率(lv)(lv)放(fang)(fang)(fang)大器(qi)(qi)(qi)(qi)(qi)是(shi)(shi)一(yi)種(zhong)能量轉換器(qi)(qi)(qi)(qi)(qi)件(jian)，它將(jiang)電(dian)(dian)(dian)源供(gong)給的(de)(de)(de)(de)直流(liu)(liu)能量轉換成為(wei)(wei)高(gao)(gao)頻(pin)(pin)交流(liu)(liu)輸(shu)(shu)(shu)出(chu)(chu)(chu)在 “低頻(pin)(pin)電(dian)(dian)(dian)子(zi)線(xian)路(lu)”課程中(zhong)已知，放(fang)(fang)(fang)大器(qi)(qi)(qi)(qi)(qi)可以按照電(dian)(dian)(dian)流(liu)(liu)導通(tong)角(jiao)的(de)(de)(de)(de)不同(tong)，將(jiang)其分(fen)為(wei)(wei)甲、乙、丙三類工(gong)作(zuo)(zuo)(zuo)狀態。甲類放(fang)(fang)(fang)大器(qi)(qi)(qi)(qi)(qi)電(dian)(dian)(dian)流(liu)(liu)的(de)(de)(de)(de)流(liu)(liu)通(tong)角(jiao)為(wei)(wei)360o，適用(yong)于(yu)(yu)小(xiao)信(xin)號低功(gong)(gong)率(lv)(lv)放(fang)(fang)(fang)大。乙類放(fang)(fang)(fang)大器(qi)(qi)(qi)(qi)(qi)電(dian)(dian)(dian)流(liu)(liu)的(de)(de)(de)(de)流(liu)(liu)通(tong)角(jiao)約等于(yu)(yu) 180o；丙類放(fang)(fang)(fang)大器(qi)(qi)(qi)(qi)(qi)電(dian)(dian)(dian)流(liu)(liu)的(de)(de)(de)(de)流(liu)(liu)通(tong)角(jiao)則小(xiao)于(yu)(yu)180o。乙類和丙類都適用(yong)于(yu)(yu)大功(gong)(gong)率(lv)(lv)工(gong)作(zuo)(zuo)(zuo)丙類工(gong)作(zuo)(zuo)(zuo)狀態的(de)(de)(de)(de)輸(shu)(shu)(shu)出(chu)(chu)(chu)功(gong)(gong)率(lv)(lv)和效率(lv)(lv)是(shi)(shi)三種(zhong)工(gong)作(zuo)(zuo)(zuo)狀態中(zhong)者。高(gao)(gao)頻(pin)(pin)功(gong)(gong)率(lv)(lv)放(fang)(fang)(fang)大器(qi)(qi)(qi)(qi)(qi)大多工(gong)作(zuo)(zuo)(zuo)于(yu)(yu)丙類。但(dan)丙類放(fang)(fang)(fang)大器(qi)(qi)(qi)(qi)(qi)的(de)(de)(de)(de)電(dian)(dian)(dian)流(liu)(liu)波(bo)(bo)(bo)形失真太(tai)大，因(yin)而不能用(yong)于(yu)(yu)低頻(pin)(pin)功(gong)(gong)率(lv)(lv)放(fang)(fang)(fang)大，只能用(yong)于(yu)(yu)采用(yong)調(diao)(diao)諧(xie)回(hui)(hui)路(lu)作(zuo)(zuo)(zuo)為(wei)(wei)負載的(de)(de)(de)(de)諧(xie)振功(gong)(gong)率(lv)(lv)放(fang)(fang)(fang)大。由(you)于(yu)(yu)調(diao)(diao)諧(xie)回(hui)(hui)路(lu)具有濾波(bo)(bo)(bo)能力，回(hui)(hui)路(lu)電(dian)(dian)(dian)流(liu)(liu)與電(dian)(dian)(dian)壓仍(reng)然極近于(yu)(yu)正弦波(bo)(bo)(bo)形，失真很小(xiao)。 ATOS放大器E-ME-AC-05F接線圖：
